The new colors make more sense from a branding standpoint. While the
old colors were more lively they don't have a "fedora" look to them.

That's true, but we should also think about the feelings of people
looking at posters of those colors. Blue is nice and cool, but gives
also "cold" sensations. Good for penguins ;-) but please let's try not
to be too monothematic. And if we add grey on two thirds of the images,
the result is very sad IMHO.
